FFICEQ HARVEY S. MUNSON, OF NEIN HAVEN, CONNECTICUT.

ROTARY CUTTER.

SPECIFICATION forming part of Letters Patent N o. 585,341', dated June29, 1897.

Application filed March 28, 1889. Serial No. 305,066. (No modelJ T0 allwhom it may concern.'

Be it known that 1, HARVEY S. MUNsoN, a citizen of the United States,residing at New I-Iaven, county of New I-Iaven, and State ofConnecticut, have invented certain new and useful Improvements in RotaryCutters, fully described and represented in the following speciiicationand the accompanying drawings, forming a part of the same.

In a companion application for Letters Patent, iiled lWIarch 28, 1889,Serial No. 305,065, I have shown and described a scoring and tubingmechanism designed to operate upon sheets of cardboard or thick paper toproduce tubes which when severed into proper lengths form the tubularsheaths or casings for what are known as slide-boxes, and particularlysuch boxes as are used for cigarettes and other similar purposes. Thetubes thus produced are made from sheets of paper of sufficient lengthto form the tubular sheaths for a number of boxes, and after the tubesa-re made in the manner described in my said companion application it isof course necessary to sever them into suitable lengths to form theindividual bozcsheaths.

The present invention relates to a cutting and delivering mechanismwhich is designed particularly to operate upon the tubes formed asdescribed in my said companion application and while they are in a flatcondition to sever them into the proper lengths for use as box-sheaths.The mechanism shown in t-he present application may, however, beusefully employed in any case Where it is desired to sever a sheet ofcardboard or thick paper into a number of short lengths and deliver thesame in separate piles.

A full understanding of the invention can best be given by anillustration and a detailed description of a mechanism embodying thesame. Such description will therefore be given, reference being had tothe accompanying drawings, in Which- Figure l is a plan View of amechanism embodying the invention. Fig. 2 is a longitudinal verticalsection of the same. detail view of the feedgage and guides of themachine, and Fig. 4 is a cross-section of the saine.

Referring to said gures, it is to be understood that a b represent pairsof cutting-disks mounted upon shafts A B, j ournaled in a suitableframework in such position that the disks work past each other with ashearing action 1n the manner common in rotary cutters.

The shafts A B are geared together and resheets of material arepresented to the disks.

The table B is provided with a number of slots d, through Which projectfingers f, which extend above the top of the table and are carried by areciprocating plate g, located beneath the table and moving horizontallyin suitable guides.

The function of the fingers f is to present the tubes to thecuttingdisks, and for this purpose the head-plate which carries theiingers is connected to a rock-arm h, which extends from a shaft 7c,mounted beneath the table and having an arm Z, which is connected by arod m to a crank n, secured upon the shaft B in such manner that at eachrevolution of the shaft the iingers f are caused to move to and from thecutting-disks.

For the purpose of presenting the tubes to the cutter in proper positionlengthwise there are provided side guides o p, which act upon the endsof the tubes. These guides are adj ustable upon a bar q, which extendstransversely of the machine above the table D, and are inclined so thatas the tube is advanced by the fingers f it will be moved longitudinallyin one direction or the other to be brought to the proper position. Oneof the guides (p, as shown in the present case) is made of spring metal,so as to yield slightly to accommodate tubes which vary in length withincertain limits.

The pairs of cutting-disks at the ends of the shafts A B operate to trimoff the ends of the tube to reduce it to the proper length, while theintermediate pairs of disks operate to sever the tube into sections ofthe proper length. The bar q, which supports the side IOO guides, isalso provided with two or more spring-fingers s, which eXtend downwardin front of the bar and rest upon the table D, so as to bear upon theupper surface of the tube as it is advanced by the fingers f. Thesespring-ngers s operate in case the tube is placed upon the table so thatone end will be moved forward slightly in .advance of the other, todetain the end thus advanced and cause the tube to be advanced evenly atboth ends and presented squarely to the cuttingdisks.

To aid the operator in feeding the tubes accurately and rapidly to themachine, the bar q is provided with a ledge t, upon which the operatorcan place the edge of the tube with one end abutting against the guideo. The operator having placed the tube in this position will hold itthere while the preceding tube is being advanced to the cutters by the-fingers s, and as soon as the fingers have been retracted the operatorwill simply release the tube, the edge of which is resting upon theledge t, allowing it to fall upon the table in front of the lingers, andby reason of the position in which the tube is held upon the ledge itwill fall naturally onto the table into substantially the properposition to be advanced squarely to the cutters.

Located upon the shafts A B between the pairs of cutting-disks are aseries of pulleys u, around which pass upper and lower conveying-tapes ow, by which the sections of the tube after they are severed from eachother are taken as they pass from the cutters and conveyed away from themachine to be deposited in suitable receptacles.

In order to separate the sections and deposit them in separat-ereceptacles, the tapes o w are arranged as follows: All of the tapes c,which are the upper tapes of the series, pass around pulleys u upon theshaft A and return around a roll or a series of pulleys x, located at asuitable distance from the cutters. The tapes w, which cooperate withthe tapes fu, pass around the pulleys u upon the shaft B and passforward with the tapes v. Alternate tapes of the series w return arounda roll or pulleys y, located directly or substantially beneath the rollor pulleys fr. The remaining tapes w, which alternate with those passingaround the roll 3j, pass forward with the corresponding tapes fr, butreturn around a roll or pulleys e, located nearer the cutters than theroll y. By this means, as will readily be seen, the several sections Einto which the tube is severed are advanced side by side between thetapes 'o w until they arrive at the roll z, as indicated in Figs. l and2. As soon, however, as they pass the roll z the alternate sections E,being no longer supported by the under tapes w, fall and enterreceptacles F, provided to receive them, where they are retained inseparate lots and can be readily counted. The remaining or alternatesections E do not fall, but pass forward between the tapes c w, asindicated by dotted lines in Fig.

l, until they emerge from between the rolls :1c y, Where they pass fromthe control of the tapes and are deposited in receptacles G, provided toreceive them.

What I claim isl. The combination with the rotary cuttingdisks ab, ofthe reciprocating feeding-fingers, the side guides o, p, one of saidguides being yielding and adjustable longitudinally of the axes of thecutting-disks, and the spring presser-fingers s, substantially asdescribed.

2. The combination with the rotarycut-tingdisks, the reciprocatingfeeding-lingers and the side guides, of the bar q having a ledge forsupporting the material previous to its being deposited in front .of thefingers, substantially as described.

3. The combination with the rotarycuttingdisks a b, of the pulleys ualternating with the disks and the alternating long and shortconveying-tapes o w for conveying the sections away from the cutters,substantially as described.

4. The combination with the rotary cutters, of the alternating long andshort conveyingtapes for conveying the sections away from the cuttersand delivering them in different positions, substantially as described.

5. The combination with the rotary cutters, the feeding-lingers foradvancing the material to the cutters, and the side guides, of thealternating long and short conveying-tapes fu,

w for conveying the sections away from the cutters, substantially asdescribed.

6. The combination with the rotary cutters, the feeding-lingers foradvancing the material to the cutters, the side guides, and the springpresser-fingers s, of the alternating long and short conveying-tapes u,w for conveying the sections away from the cutters, substantially asdescribed.

7. The combination with the rotary cuttingdisks, of the feeding-fingersfor advancing the material to the cutters, side guides o, p, one of saidguides being yielding and both of said guides being inwardly inclined,and tapes for conveying the sections away from the disks, substantiallyas described.

8. The combination with the rotary cuttingdisks a, h, of the pulleys uand pulleys x z, and alternating long and short conveyingtapes e, w, forconveying the sections away from the cutters, substantially asdescribed.

9. The combination with the rotary cuttingdisks a, b, of thereciprocatingfeeding-fingers f, the side guides o, p one of said guidesbeing yielding, the spring presser-lingers s, and alternating long andshort conveying-tapes o, w, for conveying the sections away from thecutters substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
